SMT Stencil Wiper RollsPerformance for a competitive edge

HYPERCLEAN

Background

• 70% of board defects detected at end of the line have their origins at the printing stage.• The under stencil cleaning process is critical• One of the key materials in this process is the cleaning fabric

Fabrics on the marketCellulose/Polyester Paper

mainly from China

Cellulose/Polyester hydro-entangled non-woven

Rayon (viscose)/Polyester Paper/Fabric

Polypropylene fabric (Hyperclean)

Hyperclean properties

• 100% polypropylene• No cellulose or Rayon• No linting• Low abrasion – longer stencil life

• Hydrophilic• Reduced IPA consumption • Fast and controlled wicking

• Random fiber orientation• Better vacuum performance• Mechanical trapping of solder balls – 3D structure• Less smearing

Actual Images using 400X Magnification

Cellulose/Rayon/Polyester Paper

Solder balls stay on the surface creating solder flakes & potential contamination as the solder balls

dry out.

Hyperclean

Solder balls are trapped within the fibres, thereby eliminating

contamination as the solder balls dry out.
